--; Application Julyvzi, 1949, seria1No.107,007 4 u -The principal object of this invention is to provide aheater for burning wood, coal, corncobs or the like that has an unobstructed air intake channel into the re-chamberand a baffle plate arranged therein to direct the air toward thel center of the heater into the re and thereby increasing theintensity of the fire.

'TA further object of this invention is to provide an efficient'heater. for burning wood, fcoal', corncobsor the like thatfeanbe used ei-ther as a space heater-'orA as a" water tank'heate'r' when partiallysubmerged. f e

iA-stillfurther' object of this invention is'to provide a heater for burning wood, corncobs or the'like that is economicalin manufacture, eilicient in operation and durable in use. f Y l These and other objects willbe apparent to those skilled in the art. Y l

My invention consists in the construction,'ar

v rangement, and combination of the various parts 5 Claims.l (Cl. 12S-e367) The top edgero'f this-partition is fiushfwitn the top` edge of the'housing and the bottom `edge terminates slightly :above the communicating point ofuthehousin'g and chamber, as shown in 3. yThus arranged, -the partition serves vto provide an unobstructed air channelinto the rebox. As shown in Fig. 3 the partition Eis constructed vsot-hatfthe width of the air channel is somewhat greater at the top than at thezbottom,

and this `was provided so that air drawn into the're will be directed' against' the baffle plate ofthe device,.whereby the objects contemplated are attained as hereinafter more .fully set` forth, pointed out'inmy claims, and illustrated inthe accompanying drawings, in :which:

Fig. 1 is a perspective view of this device ready fortuse,

Fig. 2.is a top view of this device with a cut away portion to Amore fully illustrate its construction, and I Fig. 3 is a cross-sectional view of this device taken'on the line 3-3 of Fig. 2 with the horizontal'intermittent line indicating a water level when this device is partially submerged in a water tank or like.

Heaters arenot new and have been used for many years' with various meansl adapted for providingandcreating draftsvto increase their efficiency. In my. invention I was motivated by a need for increasing the intensity of the fire in heaters used in watering tanks for livestock. In this situation the heater is partially submerged in an open toplwater tankand obviously the hotter .the re is, the. more efiicientthe heater will'function.; This canbe accomplished by directing a draft at the bottom `and center of the fire which I .have done in my invention that I will now describe. l

Referring to the drawings I have used the numeral I0 to designate a cylindrical housing,

having a closed bottom and an lopen top, which serves as the rebox. ,The numeral I I designates a horizontal elongated substantially rectangular, .combustion chamber havinga flat top and flatbott'om; is closed at it's'o'ute'r end and communicate's .at its other end with the sidefof the housing III near the bottomA thereof, as shown in 3.` The .numeral I2 designatesja vertical vent pipe that has its bottom portion in communication'with. the top of the chamber II near. its outer end and its vtop end in communication with I4 that is positioned at the bottom of the air channel. Thispfbailie plate |4 is Asecured to thek inside of the housing I0, as shownjin Fig. 3', and' extends inwardlyA and downwardly therefrom. By positioningv this'baffle plate at anfangle as described it serves to 'direct the air intake toward the bottom andclenterrof the rebox and thereby greatly increases the intensity of the iire.

Thev numeral I5 designates'. a circular flat lid provided with. a downwardly, extending flange member about the periphery thereof.Y .'Ihelid I 5 is hinged td'the'parttion I3 by any suitable means thatwill allow it to wbe raised-to a ninety degreeo'peningQlor more,V at times. `The numeral I6` designates a hole provided in the =lidandthe numeral Il designates a pear-shaped movable cove r..member, pivotally secured at its smaller endl-tp theutop surface of thelid I5 vso that the larger end. of the cover can be manually laterally moved to adjustably close or expose rthe hole I6 when `,desiredf-AIhe. numeral I8 designates support members suitably arranged at a plurality of points on thebottom o f this deviceandfde-f signed for -use in `securing' this device to `any supporting surface. y Y, X In r'usingl this device a fire is startedby :any suitableymeans' ,infthe bottom of. the. housing.; For'this purpose coal, wood,` corncobs or 'the like maygbe'xused. In farm-.s areas Yit. is found* that corncobs makev good ffuel, and vthereby notr'only providea `sourcetof economical vheat but I also provide a meansv for disposing'ofthe -cobs After thel nre is 'startedthe amount of fdraft throughjthe airchannel iscontrolled by the movable cover the atmosphere. The numeral I3 designatesy an elongated convex partition member that is arranged within the housing Il0 and has its longitudinal edges vertically-secured to the inside surface of the housing directly above the point where the chamber Il communicates-with the housing.

' of itliel drafticontr'ol means in the forme' on the lid andwhen the draft is opened,.thebafe plate at' the bottom ofthe air channel will direct thatair .directly into the bottom of -the rewhich greatly increases the efficiency of this heaterJfI-fy The lid I5vfi`s preferably hinged tothe housing Vto. guard against itslbecoming-lost and more "parl ticularly 'tofj4 keep it "from falling offV where vit could -becom "bentf'or "broken requiring *replacei ment inf-the latter and decreasing the efficiency The coverfI'I'; being--the'd-raft control means, 1s avr-, ranged as described so that'V when the lid isA opened for refueling the greatest maximum area` of-th housing possibleiis 'available for lling with the and`r arrangement'of. my. heaterwthout departing' from; the` real-spirit and. purpose'of' my vinvention;

modified form-s of; structure 'or use" of mechanical equivalents which may lbe reasonably included within their scope.
